I'm not sure if it is a cookie problem or not.

Posts only show as being new posts for a few minutes if someone logs directly to the forum. If they are reading news, articles etc or making submissions on the site then when they go the forum, new posts don't show at all.

Anyone know how to fix it?

I was thinking it might be a cookie issue, but as far as I know the forum is supposed to have it's own cookie.

I looked in the forum admin cp the cookie is set to mysite.com/forums should it be something else? That is the default that was left in there when I imported the db, but I had to change some other things in there to make the email function work after import and moving Nuke to the domain instead of a sub folder.

Thanks for your help
